We test the hypothesis that scientific collaboration is associated with increased publication productivity. We differentiate our approach from other studies by (a) incorporating professional networks in the productivity model, (b) casting productivity and collaboration as distinct phenomena, and (c) examining these phenomena in the context of resource-constrained research institutions in a developing country. We use survey data and employ negative binomial regression models. Results indicate that publication productivity is significantly linked to professional network factors, but there is no evidence of any association with scientific collaboration. We observe that most scientists collaborate in research projects despite coordination difficulties, and without any measurable impact on their productivity. Our interviews reveal that a possible answer to this puzzle appears to be rooted in a practice that views collaborative research projects not mainly as a means to producing knowledge and gaining recognition, but for acquiring professional opportunities and extrinsic rewards. Our findings suggest a new way of modeling publication productivity, with implications for science and innovation policy in both the developed and the developing world. 相似文献

The Brisbane Media Map is both an online resource and a tertiary-level authentic learning project. The Brisbane Media Map
is an online database which provides a detailed overview of about 600 media industry organizations in Brisbane, Australia.
In addition to providing contact details and synopses for each organization’s profile, the Brisbane Media Map also includes
supplementary information on current issues, trends, and individuals in the media and communication industry sectors. This
resource is produced and updated annually by final-year undergraduate Media and Communication students. This article introduces
the Brisbane Media Map, its functionality and systems design approach, as well as its alignment with key learning infrastructures.
It examines authentic learning as the pedagogical framework underpinning the ongoing development work of the resource and
highlights some synergies of this framework with participatory design principles. The Brisbane Media Map is a useful example
of an authentic learning approach that successfully engages students of non-traditional and non-design areas of study in human–computer
interaction, usability, and participatory design activities. 相似文献

Self-efficacy and the stages of exercise behavior change. 总被引:32,自引:0,他引:32
B H Marcus V C Selby R S Niaura J S Rossi 《Research quarterly for exercise and sport》1992,63(1):60-66
This study examined the application of constructs concerning stage of readiness to change and self-efficacy to exercise. We developed two scales to measure stages of change for exercise behavior. Prevalence information on a sample of 1,063 government employees and 429 hospital employees was then obtained. Next, the ability of a questionnaire measuring exercise self-efficacy to differentiate employees according to stage of readiness to change was tested. Results from both stages-of-change scales revealed that 34-39% of employees were regularly participating in physical activity. Scores on efficacy items significantly differentiated employees at most stages. Results indicated employees who had not yet begun to exercise, in contrast with those who exercised regularly, had little confidence in their ability to exercise. Continued work at understanding the stages of exercise behavior and exercise self-efficacy could yield important information for enhancing exercise adoption and adherence. 相似文献
